IMPROVEMENT IN LATH-MACHINES.

' Specification forming part of Letters Patent No. 146,632, datedJanuary 20,1874; application filed November 6, 1873.

To all whom it may concern:

Be it known that I, J AMES ALLEN, of Allegan, in the county of Alleganand in the State of Michigan, have invented certain new and usefulImprovements in Lath-Machines; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings and to the letters of reference markedthereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a machine for sawing laths, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to de scribe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a plan View, and Fig. 2 a side elevation, of my machine.

Arepresents the frame-work of the machine, constructed in any suitablemanner to receive the working parts thereof. B represents the fronttable, and (l the rear table, connected to gether by means of a strip,a, and attachedto the frame A by means of L-shaped metallic bars 11 I),attached to the under sides of the tables, the vertical parts of saidarms being slotted, and screws 00 90 passing through the slots into theframe. By these means the tables B (J may be raised and lowered at will,as may be desired. In the front table B is an aperture of suitable size,in which is pivoted a series of gages, I) D, having their lower endsextendingunder the table and weighted. V The weighted ends of the gagesD I) fall down, and are held by a staple, d, in such a position that theparts of the gages above the table will be gradually higher, one abovethe other, from the outer to the inner edge of the table. On the reartable 0 is a number of longitudinal guides, e e, forming spaces in whichthe laths pass. The outer edge from the outer guide e is beveleddownward, as shown at y, for the purpose of allowing the waste of thelumber to drop oif by itself, while the laths are delivered separate atthe end of the machine. By means of the gages D D the board or stripfrom which the laths are to be cut may be so gaged, no matter how wideit may be, that the waste will always be just beyond the outer guide 6,and thus keep the same separate from the laths. E E. represent a gang ofsaws set on a shaft, f, to which the power is applied. Between thesesaws. and each of the tables B and G are two feed-rollers, G and G, eachattached on the end of a horizontal shaft running across the frame A.The shaft of each of the upper feed-rollers G" has its bearings in boxesh h, each of which is placed between standards it 7:. The box nearest tothe feed-roller G is held down by means.

of a spring'rod, m, and the box at the other end of the shaft is heldbetween two pivots, t i, which allows the upper feed-roller to rise oryield, according to the thickness of the lumber passing between thefeed-rollers. At the rear end of the reartable G is a corrugated roller,II, between which and a flanged pulley, I, the laths are caught as theyemerge from between the guides c c. The flangedpuliey Iis placed upon astud or shaft at the end of a pivoted arm, J, so that the pulley willaccommodate itself to the thickness of the laths. The saw-shaft f andthe shafts of the feed rollers are connected by means of suitablegearing and the corrugated roller H is run by a belt, as shown.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The gage-bars D, each made of one piece, forming a weight at itslower end, when pivoted by a single bolt in a slot in the icedtable of alat-lrmachine, all substantially as and for the purposes herein setforth.

2. The feed-table 0, provided with guidrs e c, and having its outer edgebeveled to allow the waste lumber to fall from the feed-tame and beseparated from the laths, as set forth.

3. The combination of the ieedroller G and its shaft, the boxes h h,standards 7t 7:, spring-
